3. Heat oil in electric fry pan to 365°. Dip fingers in flour. Lift each round of dough, hold with two hands, and with two middle fingers stretch the middle of the round quite thin. This will be the depression for the jam. Quickly drop each round into hot oil, depression side down, and cover until golden brown (not dark). Quickly turn them, cover and fry until other side is golden brown. Drain doughnuts on both sides on paper towels. Fill holes with jam; dust with powdered sugar. Best if eaten warm.
